Mini Split BTU Sizing - How Many Do I Need?

Why is it important to learn ductless mini-split sizing?

So as to reap each one of some great benefits of a ductless system, you should make sure your mini-split sizing is optimized for your home. When measured properly, you'll increase energy-efficiency while lowering your monthly utility bills. As well as sizing specs, mini-splits ought to be positioned in the proper location to maximise efficiency. Understanding mini-split sizing and choosing correctly for your house can help make the best this heating and cooling investment.

What influences the sizing of the mini-split system?

You will discover three primary factors built into determining the proper sizing of your ductless ac system:

Your home's insulation levels.

The volume of warm and funky air your property is able to keep trapped inside should be taken into consideration since this insulation plays a vital role in your ductless system's overall performance.

How big the the area you're cooling.

Ductless mini-splits are sized in large part based on your capacity requirements. Larger spaces will be needing more robust units while tinier rooms can be controlled relatively easily with smaller units.

How are ductless mini-splits sized?

The industry-wide standard for sizing mini-split units is due to British Thermal Units (BTU) which are used to measure an electricity source's heat content. Specifically, it's the number of heat were required to increase one pound of liquid water with a single degree Fahrenheit or roughly the number of energy a burning match will release. When you are referring to a mini-split unit's BTU level, you're referencing its capability to cool a place efficiently. The greater the BTU number, the bigger an area the device can handle.

Although the actual sizing requirements are dependent upon the variables we discussed, here's an approximate guide tell you just how many feet square mini-splits of varying sizes can cool.
